WALTERS ATTORNEYS LOCKING BAR ASSEMBLY BACKGROUND OF THEINVENTION 1. Field of the Invention This invention relates to the fieldof locking systems. In particular, this invention relates to an improvedbar locking assembly which is substantially impervious to externalmanipulation.

2. Prior Art Locking bars for restraining the movement of a plurality ofelements using tubular locking mechanisms to control a locking pin areknown in the art. However, the prior art provides for a slot machinedaround the circumference of the moveable member locking mechanism insertinto which the locking pin is moved. By externally rotating the lockingmechanism, the locking pin may be oriented away from the face of thesurfaces which are to be restrained. A drill or other means may be usedto form a through opening from the exterior surfaces into the slot.Application of compressive force on the locking pin through the openingwill cause the pin to retract into the locking mechanism and allow themechanism to be easily removed from the moveable members. Further, inprevious art, to insert the locking mechanism within the moveablemembers, a key actuated cylinder lock had to be moved to an unlockedposition to retract the locking pin into the lock mechanism forinsertion within the moveable members. Therefore, key actuation of thelocking mechanism was necessary when placing the mechanism into themoveable members. Additionally, locking bar assemblies having extendedlocking mechanisms to provide restraint of a receptacle by blocking theexit path from a container, as well as locking bars to forceablyrestrain movement of an enclosure wall have not been found in the priorart.

SUMMARY OF THE INVENTION A locking bar assembly which comprises aplurality of relatively moveable members having respective bores passingtherethrough. One of the moveable members has a detent formed in apredetermined segment of the moveable members and adjacent to the bore.Locking and unlocking bolt means which has a translatable locking pin isslideably inserted through the bores in a specific orientation withrespect to the detent to allow translation of the locking pin into andout of the detect facing the surfaces which are to be restrained.

DISCLOSURE OF THE PREFERRED EMBODIMENTS Referring to FIG. 1 there isillustrated the preferred embodiment ofa locking bar assembly or barlock 10 to restrain displacement between relatively moveable elements l4and 16. As shown, assembly 10 is rigidly secured in a vertical mount tofrontal surfaces 17 and 18 of respective elements 14 and 16 at thevertical element interface 19. In similar fashion, bar lock 10 may behorizontally top mounted on surfaces 13 and 15 in the event moveableelements 14 and 16 are bottom hinge mounted. Additionally, locking barassembly 10 is adaptable to provide restraint forces in maintainingrelatively fixed displacement between double sliding or swinging doorsas well as restriction of motion to drawers within an enclosure, and ingeneral, to prevent relative motion between any moveable elements of asystem to be placed in some fixed relation to each other.

As shown in FIGS. 2 and 3, the preferred embodiment of locking barassembly 10 comprises moveable members or plates 20, 22 and locking boltmechanism 23 which is inserted within members 20, 22 to permit relativerotation but no displacement between respective members of assembly 10.Moveable members 20 and 22 are rigidly fastened to opposing surfaces ofrelatively moveable elements 14 and 16 by bolts or screws fastenedthrough holes 30 drilled, machined, or formed in moveable members 20 and22. Moveable member 20 has a pair of axially aligned lugs 32, 33, formedin one piece construction, and longitudinally displaced from each other.Axial bore 36 passing through lug 32 and partially passing into lug 33is of sufficient diameter to allow slideable insertion of locking boltmechanism 23. Lower lug 33 having bore 36 passing partially therethroughis cup-shaped to provide a stop or seat for locking mechanism 23 uponinsertion within moveable members 20 and 22 to prevent through passageof mechanism 23 from assembly upon insertion.

Cylindrical lug member 34 formed on moveable member 22 has a laterallength substantially equal to the longitudinal displacement between lugs32 and 33 on member in order to provide a slideable contact interfacebetween lugs 32, 33 and 34 on respective annuli when members 20 and 22are axially aligned. Axial bore 38 passing through lug 34 hassubstantially the same diameter as axial bores 36 passing through lugs32, 33 to provide a through bore of constant internal diameter whenmembers 20 and 22 are placed in an axially aligned interfacing position.In this manner, moveable members or plates 20 and 22 may be rigidlysecured to elements l4, l6 and interfaced to allow insertion of lockingmechanism 23 through bores 36 and 38, thereby providing a restraint tomovement between elements 14 and 16.

Cylindrical lug 34 in moveable member 22 has a detent 40 formed thereinadjacent to axial bore 38 and substantially orthogonal to thelongitudinal axis of bores 36 and 38. Detent 40 is formed within wall 39of lug 34 adjacent to arial bore 38 and being discontinuous with respectto a transverse contour line of wall 39. Angular orientation of thesingular detent 40, as shown in FIG. 3, is positioned to face members 20and 22 and substantially directed toward elements 14 and 16 or any othersurfaces to which members 20, 22 may be attached. Specific placement ofdetent 40 and positioned at a predetermined angular orientation withinwall 39 of lug 34 in the manner shown and described provides a lockingapparatus that is impervious to external manipulations which may movelocking mechanism 23 to an unlocked position thereby permittingslideable retraction of mechanism 23 from bores 36 and 38.

Locking bolt mechanism or assembly 23 illustrated in FIGS. 3 and 4comprises cylindrical tube 26 containing a cylinder lock 54 and lockingbolt 24 to slideably receive tube 26. Locking assembly 23 is slidablyinsertable within bores 36 and 38 of members 20 and 22. Locking bolt 24as shown in FIG. 4 includes tubular element 44 having a centrally boredpassage 42 of constant internal diameter passing therethrough along thelongitudinal axis, and cylindrical base member 46 of solid one piececonstruction, having an external diameter substantially equal to theexternal diameter of tubular member 44. Referring to FIG. 5, lateralsurface 47 of base member 46 is tapered to upper surface 49 having adiameter slightly less than that of internally bored passage 42.Tapering in this way allows base member 46 to be force fit into element44. Once constructed, locking bolt 24 is cup-shaped, having alongitudinally extended cylindrical base 46. Locking bolt opening 48formed in, and extending through the lateral wall of tubular element 44is aligned with detent 40 on lug 34 of moveable member 22. Specificangular orientation of locking bolt opening 48 with detent 40 isaccomplished, as shown in FIG. 6, by extension element 50 formed in apredetermined angular displacement on lug 34 to slideable contact grooveor slot 52 longitudinally formed within cylindrical base member 46 oflocking bar 24. The relative positioning of slot 52, bolt opening 48 andextension element 50 is such as to permit axial alignment betweenlocking bolt opening 48 and detent 40 in lug 34 when locking bolt 24 isinserted through bores 36 and 38 of moveable members 20 and 22.

Cylindrical tube 26, of diameter sufficient to allow slideable insertionwithin centrally bored passage 42 of locking bolt 24 contains thelock-unlock mechanism. Cylinder lock 54 as shown in FIG. 4 is internallysecured within tube 26 on one end thereof. Cylinder lock 54 is actuatedby insertion and rotation of key 28, being standard in operation and notpart of the invention concept as detailed by this invention. Tubepassage 56 is formed in a lateral surface and passes through a lateralwall of tube 26. Passage 56 is of substantially the same diameter butslightly in excess of locking pin 58 to allow translation of pin 58through tube passage 56 relative to the lateral wall of cylindrical tube26 whether pin 58 is being ejected from tube 26 or retracted from detent40 located within a portion of wall 39 adjacent to base 38 and beingdiscontinuous with respect to a closed perimeter line of wall 39.

In the assembly of locking mechanism 23 into a onepiece assembly,cylindrical tube 26 is slideably inserted into centrally bored passage42 within locking bolt 24 until locking pin 58 is axially aligned withlocking bolt opening 48 to permit passage of locking pin 58 throughopening 48 and finally into a locking position within detent 40 of lug34. Locking pin 58 is moveable with respect to locking bolt 24 in adirection substantially normal to the longitudinal axis of bolt 24 asshown in FIG. 8. Locking pin 58 is cylindrical and formed in one piececonstruction having a race or slot 62 machined into a lateral wallthereof. Rear cylinder end 64 and forward cylinder end 68 havesubstantially the same external diameter and are connected by stem 66having a diameter less than members 64 and 68, depressed by the annularwidth of race 62. Locking pin bore having a smaller internal diameterthan stem 66 is drilled longitudinally within locking pin 58 from rearcylinder 64 passing into but not through forward cylinder end 68.Internally placed within locking pin bore 70 is helical spring 71longitudinally inserted to contact forward cylinder end 68 with lockingpin bore 70 on one end and on the opposing end in a depression 72 formedwithin cylindrical tube 26 as shown in FIG. 8. Depression 72 provides ashoulder or placement for spring 71 to prevent movement of spring 71relative to the internal wall of tube 26. In this manner, helical spring71 applies a contact force to locking pin 58 in an outward directionwith respect to the lateral walls of tube 26. This force has the effectof providing a directionally oriented positioning of locking pin 58 in adirection normal to the longitudinal axis of locking mechanism 23 in anoutward manner with respect to the lateral walls of tube 26 and lockingbolt 24.

Translation of movement of locking pin 58 with respect to locking bolt24 and tube 26 is accomplished by actuation of rod member 60 rotated inresponse to key 28 rotation within cylindrical lock 54. As is seen inFIG. 8, rod member 60 extends into race or slot 62 and contacts rearcylinder end 64. Since spring 71 provides a force in an outwarddirection, rod member 60 is at all times contacted by rear cylinder end64.

Rotation of key 28 in cylinder lock 54 provides the means whereby rodmember 60 may be rotated to a first locked position or to a secondunlocked position. The first locked position of rod member 60 and secondunlocked position of rod 60 are shown in FIGS. 8 and 10. When rod member60 is in a locked position, locking pin 58 extends through tube passage56, locking bolt opening 48, and into detent 40. Rotation of key 28within cylinder lock 54 responsively rotates rod member 60 to a secondunlocked position where the locking pin 58 is released from detent 40 oflug 34, illustrated by dotted lines in FIGS. 8 and 10.

The dimension of race or slot 62 in a longitudinal direction withrespect to locking pin 58 is such that when rod member 60 is in thesecond locked position and contacting rear cylinder end 64, thelongitudinal displacement between rod member 60 and forward cylinder end68 is less than the extension of forward cylinder end 68 from tubularelement 44 of locking bolt 24. When locking mechanism 23, comprisingcylinder tube 26 and locking bolt 24 are to be inserted into bores 36and 38 in members 20 and 22, locking pin 58 cannot be manually forcedflush with the external lateral surface of tubular element 44.Therefore, insertion of locking bolt 24 within bores 26 and 28 must beaccompanied by insertion of key 28 into cylinder lock 54 and anappropriate rotation of rod member 60 to a second unlocked position asshown in FIG. 8 where locking pin 58 may be manually depressed flushwith the external surface of tubular member 44 and then slidablyinserted into bores of members 20 and 22.

In an embodiment of the inventive concept as shown in FIG. 10, thelongitudinal width of race 62 is extended in order that the displacementbetween rod member 60 and forward cylinder end 68 when rod member 60 isin a first lock position is such that .this distance is equal to theextension of locking pin 58 from tube member 44 of lockfing bolt 24. Theincrease of the longitudinal race width over that illustrated in FIG. 8permits locking pin 58 to be manually forced flush with the externalsurface of tubular member 44 without actuation of cylinder lock 54 tothe second unlocked position of rod 60 when locking mechanism 23 isslideably inserted through bores 36 and 38. In this embodiment, anoperator may restrain moveable members 20 and 22 by insertion of lockingmechanism 23 without the need of any key actuation of cylinder lock 54as opposed to the preferred embodiment where cylinder lock 54 isactuated to move rod 60 into the second unlocked position andcylindrical tube 26 containing cylinder lock 54 is inserted into lockingbolt 24. Upon insertion, tube 26 is angularly rotated until locking boltopening 48 is aligned with locking pin 58 extending from cylinder tube26 through passage 56. Locking pin 58 is manually depressed and lockingmechanism 23 is inserted into axial bores 36 and 38 within moveablemembers 20 and 22. Groove or slot 52 in cylindrical base member 46 ispositioned to slideably insert within extension element 50 on lug 34 ina manner such that when locking bolt 24 is slideably inserted, lockingpin 58 is axially aligned with detent 40. Detent 40 is directionallylocated adjacent to axial bore 38 and oriented in a directionsubstantially towards the surface to be restrained. The directionalplacement of detect 40 now provides a safeguard in locking bar assembly10 wherein the drilling through the wall of lug member 34 in moveablemember 22 will not allow depression of locking pin 58 to provide removalof locking bolt 24.

In another embodiment of the invention, as shown in FIGS. 11 and 12,fare box or receptacle 74 is restrained within enclosed frame 76.Frontal member 78 is slideably or otherwise removable providing frame 76with a frontal opening to permit removal or insertion of fare box 74. Inthis configuration elongated locking bolt 84 passing horizontally acrossthe frontal opening contains box 74 within frame 76. Housing or bushing80 is rigidly attached to forward frame wall 82 having a centrally boredthrough passage of sufficient diameter to permit slideable entrance ofelongated locking bolt 84. Strike 86 having a central passage partiallydeveloped in the longitudinal direction to accept entrance of elongatedlocking bolt 84 is rigidly fastened to rear frame wall 88 and passestherethrough. Tubular member 87 is force fit into base member 90 havinga groove in the longitudinal direction to slideably engage extensionelement 92 of strike 86. Engagement of extension element 92 with thelongitudinal groove in base member 90 angularly orients elongatedlocking bolt member 84 in such manner as to axially align locking pin 94of locking mechanism 96 with an opening 98 in housing 80. In thismanner, box 74 is restrained from movement through the frontal openingwhen frontal member 78 is removed. Retraction of locking pin 94 fromopening 98 and removal of elongated locking bolt 84 provides a passagewhereby box 74 may be removed from enclosed frame 76.

In still another embodiment of the invention shown in FIGS. 13 and 14, abox or coin assembly 100 is situated within an enclosed housing 102having upper wall 109 which may be relatively displaced by rotationaround hinge member 104 thereby providing a top opening through whichcoin assembly 100 may be removed from the interior of housing 102.Strike or tab 106 is rigidly secured by weld or other means to upperwall 109 and passes therethrough. Strike 106 has a through passage 108of sufficient diameter to accept insertion of locking bolt 110. Bushing112 having a central passage 114 of sufficient diameter to acceptlocking bolt and substantially equal in diameter to through passageway108 of tab 106 is secured to forward housing wall 116 and has an openingpassing through a lateral wall to permit entrance of locking pin 118 oflocking mechanism 120. Locking bolt 110 is slideably restrained withinbushing 112 by set screw 111 inserted through a lateral wall of bushing112 and extending into a longitudinal slot formed within a lateral wallof bolt 1110. In this manner bolt 110 may be slideably moved relative tobushing 112 but not removeable therefrom.

Insertion of locking bolt 110 within through passage 108 of strike 106provides a restraint to any rotational displacement of upper wall 109with respect to housing 102. Box 100 is then restrained within housing102 and cannot be removed. Unlocking of locking mechanism 120 byretraction of locking pin 118 allows removal of locking bolt 110 fromstrike 106 to provide relative movement capability of upper wall 109 andremoval of box 100.

attached to rigid frame 125. Positioning of opening 124 may be on anysurface of box 122 convenient for collection of coins. Box base 126slideably moves within tracks 128 rigidly attached to frame 125 toprovide means of insertion and removal of box 122 with respect to rigidframe 124 having one exit and entrance path for cash box 122.

Bushing 129 having an axial bore passing through it is rigidly attachedto frame wall 130 by weld, bolts or other rigid attachment not importantto the invention. Locking bolt 132 is slideably insertable through theaxial bore of bushing 129 and is of sufficient length to intersect theentrance and exit path of cash box 122. Locking mechanism 134, asdescribed in preceeding paragraphs, has locking pin 136 to be insertedwithin a recess of bushing 129 when locking bolt 132 is extended intothe path of cash box 122 thereby preventing removal of box 122 whenmechanism 134 is placed in a locked position. Set screw 138 passingthrough lateral wall 140 of bushing 129 interacts and is slideablewithin groove 142 which is longitudinally formed in locking bolt 132. Inthis manner, locking bolt 132 is slideable with respect to but notremoveable from bushing 129. Groove 142 is of sufficient length topermit insertion and retraction of bolt 132 to and from the entrance andexit path of box 122 when locking pin 136 is in a retracted positionwith respect to the recess formed within bushing 129. In similar fashionto other embodiments of the invention where pin 136 is inserted into therecess of bushing 129, bolt 132 is in a locked position to restrainmovement of box 122 with respect to rigid frame 125.
